To all whom it may concern:

Be it iknewn that I, ELMER,C. JDIT1M}R, a

citizen of the United, States, residing atlVilliamsport, in the; county of jLycomlng; 5 and State of Pennsylvania,have nventedrertain new and," useful; Improvements in Burnishers for Machines for li inish-ing- Flooring, off which the following is a specification, reterencebeinghad therein to the accompanying drawing. 7

This invention relates to certain new and useful improvements in burnishers for burnishing the face of a finished strip of lumher in its passage through a machine; for 1 preiinishing flooring and the like as disclosed in my companion applications, the object being to provide novel means for yielding-1y holding the burnisher at an angle to the face of the strip being finished.

Another and further object of the invention is to provide aburnisher in which a coil sprirn is employed to hold the burnishing members, the burnishing members being disposed between. the convolutions of the spring in such a manner that they will be held firmly therein and in a yieldable manner so that they will engage the surface of the strip in order to burnish the face properly.

In my companion applications above referred to for preiinishing flooring, a series of glass burnishers are employed as I have found in practice that glass burnishers obtain better results than any other material and in practice these burnishers sometimes break when rigidly held or when tension is applied to the same and the object of this invention is to overcome this disadvantage as by mounting the strips of glass between the convolutions of the spring, they are held firmly and are allowed to yield so that the proper burnishing effect is obtained on the surface being treated.

Other and further objects and advantages oit'the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings,

Figure l is a top plan View of a burnisher constructed in accordance with my invention showing the same in position in respect to the strip being burnished; and

Figure 2 is a vertical transverse section through the burnisher showing the manner of mount ng h i me n an djus ab e sup por .v

In carrying out my invention I employja tangul r shaped i ml erior, box-l ke me ter d. iby n adju table support W; h e1 bl .e ea lderv o i e a ine. to the material being operated on.

Arranged within the box like member 1 is a coil spring 5 held in position therein by metal strap 6 which passes through the spring and has its ends extended through suitable openings formed in the end of the box like member and bent back upon the outer wall thereof as shown at 7 so as to fasten the spring in its proper position within the box like member.

Disposed between the convolutions of the spring 5 are a series of glass burnishers 8 which hold the burnishers at an angle in respect to the face of the strip of material 9 being burnished as clearly shown in Figure 1 and in practice a glass burnisher is disposed between every other convolution so that the burnishers are yielda-bly held so as to prevent the breaking of the burnishers when pressure is applied to the same by adjusting the movable support in respect to the moving strip of lumber.

From the foregoing description it will be seen that I have provided a burnisher to be used in connection with burnishing strips of finished lumber composed of a coil spring having glass burnishers disposed between the convolutions thereof so as to form a yieldable support for the glass burnishers.

By constructing a burnisher in the particular manner shown, the glass burnishers disposed between the convolutions of the coil are held at an angle to the face of the strip being polished so that they will yield in order to prevent the breaking of the glass burnishers and I have found in practice that a burnisher constructed a shown obtains a better lnirnishing effect upon the finished strip of lumber as the desired pres sure can be applied to the burnishers without any danger of breaking the same.

means for adjustably supporting said resiL i'ent member.

2. A burnisher for wood finishing machines comprising an adjustable support, a coil spring carried by said support and a series of burnishers disposed between the convolutions of said spring.

8. A burnisher for wood finishing machines comprising an adjustable support, a box-like member mounted upon said support, a coil spring mounted Within said box-like member and a series of burnishers disposed between the convolutions of said sprin 4. A burnisher for wood finishing machines comprising a coil spring having a series of glass burnishers disposed between the convolutions thereof.

5. A burnisher for wood finishing ma- 20 chines comprising a coil spring having a glass burnisher disposed between every other convolution thereof.

6. A burnisher for wood finishing machines comprising a supporting member having a coil spring secured thereto by a strap extending through said spring and a series of glass burnishers disposed between the convolutions of said spring.

7. A burnisher for wood finishing machines comprising a resilient supporting member having a rigid burnisher embedded therein.

8. A burnisher for wood finishing machines comprising a coil spring having a rigid burnisher mounted between the con- Volutions thereof.

In testimony whereof I hereunto aflix my signature.
